Struct Announces September 30 Shutdown for its Polymarket APIs and Explorer

By Polytoolhub · Updated 2026-10-01

In a September 17, 2026 statement, Struct announced that all its Polymarket APIs and Explorer would be permanently shut down on September 30 at 23:59 UTC. The statement asks customers to migrate data and integrations. Check the official service status and complete migration checks before relying on a replacement integration.

Who needs to check an integration

An operator relying on Struct endpoints, webhooks or Explorer data should check the vendor's notice and their own dependencies before the announced time. The directory does not have access to customer accounts, request logs, credentials or a live Struct integration; its September 7 feature and $49 pricing notes are historical and were removed as current catalog facts.

Other documented data tasks are not drop-in replacements

Polymarket's official overview documents Data API positions/activity and CLOB books and signed order operations as distinct surfaces. Their existence does not guarantee compatible Struct schemas, historical coverage, entitlement, costs or an automatic migration. Check each target's current documentation and expected fields rather than copying private credentials between services.

Migration checklist

Treat the announced cutoff as a migration deadline. Check which endpoints your app uses, export the data you need and validate identifiers, response fields and historical coverage with your replacement provider.

Service availability

The announced cutoff is now in the past. The vendor notice still describes that schedule; this directory has not independently observed endpoint shutdown or billing outcomes.
